CHILLED WATER SYSTEMS
In HVAC, chilled water units can be categorized into several types based on their design, application, and functionality. Here are some common types of chilled water units:
Air-Cooled Chillers
These chillers use air-cooled condensers and are often used in smaller applications.
Water-Cooled Chillers
These chillers use water-cooled condensers and are commonly used in larger commercial or industrial applications.
Centrifugal Chillers
These chillers use centrifugal compressors and are often used in large commercial or industrial applications.
Screw Chillers
These chillers use screw compressors and are commonly used in medium to large-sized applications.
Reciprocating Chillers
These chillers use reciprocating compressors and are often used in smaller applications.
Scroll Chillers
These chillers use scroll compressors and are commonly used in small to medium-sized applications.
Absorption Chillers:
These chillers use heat energy to drive the cooling process and are often used in applications with waste heat or steam.
Steam-Driven Chillers
These chillers use steam to drive the cooling process and are often used in applications with available steam.
Electric Chillers
These chillers use electric motors to drive the compressors and are commonly used in most applications.
Hybrid Chillers
These chillers combine different cooling technologies, such as absorption and electric chillers.
Chiller System Configurations
The configuration of your chilled water system can be tailored to your operational needs for capacity and redundancy:
- Single-Chiller Systems: A single chiller provides cooling for the entire facility. This is common in smaller applications where simplicity and lower initial cost are priorities.
- Multiple-Chiller Systems: Two or more chillers are used to provide cooling. This setup offers enhanced reliability, redundancy (backup capability), and improved efficiency, as chillers can be staged to match the building’s exact cooling load.
The experts at Workman Services UAE can help you assess your cooling requirements, building size, and efficiency goals to design and install the ideal chilled water system for your needs.
